Shen Hengzhi opened her eyes. The dilapidated house was leaking and the rice jar was bottomed out. The three girls of the Shen family are extremely poor. Fortunately, there is an interstellar farming system to lay the groundwork - seedlings can be produced overnight, but it will be a headache for three days. Is the land fertile enough? Plant milkvetch to fix nitrogen. The neighbors laughed at her for messing around. She squatted at the head of the field with her palms on the ground, rubbing the joints of the withered vegetable seedlings until they were shiny green. Grain merchant Qian Wanguan lowered grain prices, threatening that "all the paddy fields in Qingxi County must obey my orders." Shen Hengzhi turned around and used interstellar algae fermentation liquid to revive the entire mulberry forest infected with the plague. Silk sellers rushed to place orders, and money poured into their accounts. Her husband, Zhou Jinrong, was immersed in reading, but his hands were frozen due to copying. She gave birth to a hemostatic grass, pounded it and applied it on it, and taught him to identify astronomical calculations through star charts at night. Before the rural examination, the grain merchants colluded with the gate officials to jam the grain transport ship, and the whole village was shut down. Shen Hengzhi and his family dug canals overnight, reinforced the dams with tree roots, and forcibly created new waterways. On the day when the results were released, Zhou Jinrong stood at the head of the desk and looked back to see her hands covered with mud. She smiled and showed a stack of land deeds: "Mr. Sir, Qingxi Grain Store has opened for business." The whole family was reunited and life was hot. But the interstellar system's alarm suddenly went off: you only have three years left to live.
